Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery using a wrench to prevent any electrical shorts during repairs.

2. Battery Inspection

Tools Required: Multimeter, wrench set
Sub-steps:
1. Connect the multimeter leads to the battery terminals (red to positive, black to negative).
2. If the voltage is below 12.4 volts, recharge or replace the battery.
3. Clean any corrosion from the battery terminals using a wire brush and a mixture of baking soda and water.
4. Tighten the battery connections securely.

3. Starter Motor Check

Tools Required: Multimeter, jumper cables
Sub-steps:
1. Locate the starter motor under the vehicle.
2. Disconnect the electrical connector from the starter motor.
3. Use jumper cables to supply power directly to the starter motor to check if it engages.
4. If the starter motor does not engage, replace the starter motor.

4. Ignition Switch Inspection

Tools Required: Screwdriver set
Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Disconnect the wiring harness from the ignition switch.
3. Use a multimeter to test for continuity across the switch terminals when the key is turned to the "Start" position.
4. If there is no continuity, replace the ignition switch.
